I too am wondering what this setting actually does. The manual addendum says:

Added [Ambient Brightness]It has two options: [Original] or [Normal] (The default setting is [Normal]). [Original] enables you to take pictures with the ambient light quantities comparable to those of the GR film cameras. In this mode, ORIG ￼appears on the shooting screen.

I wonder if this setting is playing with the exposure setting or doing something on the lines of what the Dynamic Range option does?

Mhm, really don't know.. From what I understand, however, only works on jpeg.
